bow parts.

A further object of the invention is to provide means adapted to be associated with both the frog and. tip of a bow, whereby the extremities of the hairs are held for tensioning.

A.further object of the invention is to provide means for banking the hairs by applying to each end thereof a clip of metal or some equivalent material, which will firmly hold the hairs in relation, and will also serve to hold the hank of hairs in the attaching members in the bow.

A further object of the invention is to provide specific types of attaching members to be associated with the frog and tip of a bow.

The invention, therefore, comprises in combination with a bow, which includes the usual adjustable tensioning frog and tip, of means for quickly and readily attaching and removing a hank of hairs to the frog and tip, which in one instance will be parts integral with said frog and tip, and in another instance, will be separable therefrom, said hank of hairs being provided with clips at its extremities, properly proportioned to make connection with the frog and tip parts provided for holding said hank.

In the drawing:

Figure l is a view of a bow in side elevation having the removable members applied thereto,

Figure 2 is a View of the bow in plan of the type shown at Figure 1,

Figure 3 is a plan view of the attaching member to be associated with the frog,

Figure 4 is a view of the attaching member shown at Figure 3 and taken from the end, as indicated by arrow 4 at Figure 3,

Figure 5 is a plan view of the tip attaching member,

Figure 6 is a view in side elevation of a different embodiment of the invention, and

Figure 7 is a view in plan of the hank of hairs and clip extremities.

Like reference characters indicate corresponding parts throughout the several views.

In one of its forms the present invention is adapted to be associated with a violin bow of the usual present approved construction embodying the bar 10 with tip 11 and frog 12 sliding thereon. The frog is adjusted longitudinally of the bar 10 in the usual wellknown manner, merely illustrated by the head 13 which actuates the screw (not shown).

1933, Serial No. 654,798

An attaching member is provided for the frog having a plate portion 14 which bears directly upon the face of the frog and wings 15 converging to correspond with the formation of the usual.

frog, now well-known, and to form a dovetailed connection therewith. The securing member is provided with an end wall 16 which engages against the end of the frog to limit the sliding movement of the attaching member thereon.

This attaching member is provided with an opening 17, being wider at one lateral side 18 than at the opposite lateral side 19, the purpose of which 'will be hereinafter more fully explained.

The attaching member for the tip comprises a plate-like part 20 having a downwardly inclined loop 21 which fits over the point of the tip. This member is provided with an opening 22 which is of greater dimension longitudinally of the member than transversely.

As will be noted, especially from Figures 3 and 5, the lateral dimension of the opening 22 is less than the lateral dimension of the opening 17 for a purpose which will be hereinafter more fully described.

As a variation or modification of the foregoing, the bow will be made with a plate 23 permanently attached to and a part of the frog, and with a plate 24 similarly made a permanent part of the tip. These plates 23 and 24 have openings 17 and 22 therein, in all respects similar to the openings shown at Figures 3 and 5.

For cooperation with either type, a hank of hairs 25, uniformly tensioned, is bound by terminal clips 26 and 27. It will be noted that the clip 26 is wider than the clip 27, and that the hank of hairs at that end is, therefore, correspondingly wider. This is designed to be applied to the frog end of the bow. Its application is by inserting the clip 26, as indicated in dotted lines at 26' in Figure 3, with the narrower clip 27 inserted as indicated at 27' in Figure 5.

The clips are respectively wider than their respective openings, so that being inserted at an angle, as illustrated at Figures 3 and 5, and turned to their operative position, the edges of the clips extending beyond the lines of the hank will engage the undersides of the fastening members and be retained thereby.

The particular angles as shown at Figure 1 or 6 is no indication of the actual angle which will be assumed by the clips when in position, as the parts may be varied to such an extent in their relative sizes,'shapes and interconnections that the positions of these clips, when in operative position, may be quite different from the positions shown at Figures 1 and 6.

In any event, by sliding the frog along the bar toward the tip in the usual well-known manner, the tension upon the hairs is lessened to such an extent that first one and then the other of the clips may be turned to an angle to be withdrawn from its particular opening and then the other similarly turned and withdrawn.

In this position the new hank of hairs provided with its clips will be inserted, the first end, then at the other, and the tension applied thereto by the movement of the frog.

Of course, in the type showing the removable fastening members the hank may be applied to the fastening member 20 before it is applied to the bow and may be applied and hooked over the tip after the hank has been applied thereto, later, the opposite end of the hank being applied as disclosed.

It will be obvious that the type shown at Figures 1 and 2 are intended to be applied to bows already in use or manufactured, while the type shown at Figure 6 is intended for new bows to be hereinafter manufactured to include the fastening members for cooperation with the hank of hairs and clips, as described. 7

Of course the violin bow herein described may be modified and changed in various ways without departing from the invention herein set forth and hereinafter claimed.

I claim:--

1. The combination with a violin bow comprising a bar having a fixed tip and a movable frog mounted thereon, said frog presenting a dovetailed contour, of a member having converging sides complementary to said dovetailed parts and with an extremity overhanging the frog in the direction of the tip, a plate having a downwardly inclined loop proportioned to hook over the point of the tip and a plate part to extend along and beyond said tip toward the frog, both said extensions being provided with perforations each having a dimension greater than its transverse dimension, and a hank of hairs having clips permanently secured to its opposite ends, said clips being wider than the perforations in said attaching members and insertable therein by initial occupation of the greater dimension.

2. The combination with a violin bow comprising a bar having a fixed tip and a movable frog mounted thereon, of a member having an extremity overhanging the frog in the direction of the tip, a plate in part extending beyond said tip toward the frog, both of said extensions being provided with perforations each having a dimension greater than its transverse dimension, and a hank of hairs having clips permanently secured to its opposite ends, said clips being wider than the perforations in said attaching members and insertable therein by initial occupation of the greater dimension. 7
